Use a stored spark (flash suit or blue suit) to spark left through the Speed blocks. If Speed Booster is available, run to the right and back to get blue speed to go through the rest of the Speed blocks. Otherwise use Morph with either Spring Ball, Bombs, or Power Bombs to navigate above them.

If performing the spark with low energy, there is a risk of ending the spark above the spikes or in front of the Pirate; to be safe, assuming Samus has heat protection, begin the shinespark at the door (in either this or the other room) with between 81 and 96 energy, or at least 113 energy; with a buffered crumble jump to the right, up to 102 energy can work.
